Orange tree name ‘Villa11’

ABSTRACT

A new orange tree named ‘Villa11’ characterized by its late-maturing fruit.

Latin name: Citrus sinensis.

Common name: Navel Orange.

Variety denomination: ‘Villa11’.

BACKGROUND AND SUMMARY OF THE VARIETY

‘Villa11’ is a new orange tree, originally discovered in a cultivatedorchard near Leeton, New South Wales, Australia in 2015. It is believedto be a spontaneous whole tree mutation of the ‘Cara Cara’ orangevariety (not patented). The ‘Villa11’ tree was first noticed because itsfruit was greener than the fruit on surrounding ‘Cara Cara’ trees. Uponcontinued observation, the fruit was found to mature at least two monthslater than ‘Cara Cara’. The new variety was asexually propagated bygrafting in 2015 at Leeton, and has since been found to remain true totype over successive asexually propagated generations.

‘Villa11’ is distinguishable from similar varieties ‘Cara Cara’ and‘Kirkwood Red’ (U.S. Plant Pat. No. 24,778) by its late fruit maturity.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs were taken in 2019 at Leeton, NSW,Australia. The trees depicted were planted in 2015. The colors of theclaimed variety may vary with lighting conditions. Color characteristicsof the variety should therefore be determined with reference to theobservations described herein, rather than from these illustrationsalone.

DETAILED BOTANICAL DESCRIPTION

The following detailed botanical description is based on observationsrecorded at Leeton, NSW, Australia from 2015 to 2020. The treesdescribed were planted in 2015 on ‘Troyer Citrange’ rootstock (notpatented). The characteristics described will vary somewhat dependingupon cultural practices and climatic conditions, and can vary withlocation and season. Quantified measurements are expressed as an averageof measurements taken from a number of individual plants of the claimedvariety. The measurements of any individual plant or any group of plantsof the variety may vary from the stated average. Colors are describedwith reference to The Royal Horticultural Society Colour Chart (6thEd.).
